On a purely personal note, this whole mess has been depressing. I'm not a rich man, and splurging on a fancy mouse was a real treat for me. It's hard to see this much money go to waste on a piece of junk.

Just about everything about this mouse is great; Good shape, good button layout, feels good to use; In every respect save reliability, this is probably the best mouse I've ever used

The mouse randomly cuts out or stutters while in use; At first I thought it might be an issue with the surface I was using it on, or maybe I was letting the battery get too low; But the problem persists even when I've confirmed the thing is fully charged, and no matter what surface I use it on.

The best mouse I've ever owned. The locked to free scroll mode (when you flick the wheel hard enough) is super useful and with the range of options available on the buttons and side scroll means that you can change it to suit your needs

Works well, good functionality, comfortable to use, good quality, comes with good software to change preferences. The only problem is, the Flow function doesn't work for me.

The MX Master 2S lets you cut-and-paste files, portions of images, and text directly between several connected computers using new, overarching Logitech software. If this is handy in your work, this "Flow" feature might outweigh this good mouse's hefty price.

Unique cut-and-paste function between paired computers; Solid ergonomic design; Laser sensor tracks on most surfaces; Connection-swapping among up to three paired devices; Recharges one full day in three minutes

Pricey; No lefty version; Gesture "button" is concealed in the thumb rest; Button to switch connections is under mouse

While productivity mice may not have the flash of their gaming counterparts, I found the MX Master to be a worthwhile companion with a lot of intelligent features and very few drawbacks.

Comfortable design; Smart gesture controls; Functional software; Long battery life

Tiny thumb buttons; Lackluster scroll wheel

It is my 5th Logitech MX mouse. I also have a MX anywhere 2S. I've been using MX mouse since it was first launched. It never disappointed me. Super comfortable and smooth.

I have paired this with the dongle on my notebook and via Bluetooth for my Surface and have had no issues, also has a great response rate for spanning multiple monitors.

Logitech really nailed everything with this mouse. Quality craftsmanship, satisfying crisp clicks all around, very good wheel (something often overlooked). Comfortable to hold and nice choice of materials. For desktop use, this is pretty much one of the best out there.

Very well built - sublime clicks, excellent wheel (consistent sound and feel both up and down); Nice middle click with moderate force; All round very sturdy and quality construction; Quality plastic/materials; Feels comfortable to the touch and doesn't show marks/stains from skin oils.

Arch is higher than most mice; so might be a comfort issue for some people (hasn't bothered me though)

Logitech's latest mouse takes a radical departure from previous designs, with a large thumb-rest, and polygonal artistic flourishes. It sure looks striking, and in the hand it all comes together to offer a mouse that feels very comfortable for even all-day computing.

Awesome mouse, solid battery, (2 weeks = solid 6 hours per day) and extremely comfortable. Im on mac for work, and really take advantage of the customisable gesture button (under the thumb).
